From f141f631e23a487ef745c0ff8faf9fee2cca570e Mon Sep 17 00:00:00 2001 From: Nathan Maine Date: Sun, 29 Mar 2026 16:38:40 -0500 Subject: [PATCH 1/4] feat: add fabricated regulatory citation prompts to misleading probe Add misleading.FabricatedRegulatoryCitation with 25 prompts referencing nonexistent regulatory controls (NIST SP 800-171, CMMC, DFARS, HIPAA) to test whether models fabricate authoritative responses rather than refuting false premises. Reuses MustRefuteClaimModel and MustRefuteClaimKW detectors. Set to active=False (domain-specific).

The previous form was malformed rather than merely nonexistent, which contradicted the claim that identifiers follow real framework numbering. Collision safety is unchanged: XX is an unassigned domain, Levels 4 and 5 are above the CMMC 2.0 maximum, and 3.9x is above the 800-171 family range. - doc_uri points at Dahl et al., Large Legal Fictions (arxiv.org/abs/2401.01301), whose section 5.2 scores any uncritical answer to a premise false by construction as a hallucination, matching this probe's rule. The inherited reference describes activation-based lie detection and does not cover this technique. - prompts_per_framework raised to 6, so default output is 30 prompts, meeting the bar in docs/source/extending.probe.rst - Docstring records that identifiers are sentinels rather than realistic, that difficulty varies across frameworks, that per-framework volume is capped by range size, and that the module's detectors were tuned on a different register, following the limitation note on the sibling smuggling.HomoglyphObfuscation probe - Say "target" rather than "model" in the docstring, goal, and intent comment, per AGENTS.md - Drop the active and tier assertions, which test default values of a configurable plugin against AGENTS.md guidance - Fix the determinism test, which compared a memoised plugin instance with itself and could not fail; it now instantiates the class directly Co-authored-by: Claude Signed-off-by: Nathan Maine --- garak/probes/misleading.py | 69 ++++++++++++++++++-------- tests/probes/test_probes_misleading.py | 15 ++---- 2 files changed, 52 insertions(+), 32 deletions(-) diff --git a/garak/probes/misleading.py b/garak/probes/misleading.py index 5c268bb4a..5f524276f 100644 --- a/garak/probes/misleading.py +++ b/garak/probes/misleading.py @@ -16,11 +16,13 @@ from garak.data import path as data_path import garak.probes -# Identifier syntax for real compliance frameworks, paired with numeric ranges -# that fall outside each published standard.
